Terminals are asking but that doesn't mean people are tipping, as the article points out:

> People are tipping less at restaurants than they have in at least six years, driven by fatigue over rising prices and growing prompts for tips at places where gratuities haven’t historically been expected.

15%? Where I live it starts at 18%. Before we swiped/taped our own credit cards a tip at chipotle was unheard of. I go to Hanlon's razor here though. The POS system just defacto has this screen and no one removes it because some people do tip.

If I walk up and order something that doesn't require labor to make and I bus my own table and throw away my own trash, I don't tip. The business owner pays the staff from what I pay for the food. If not I'll cut the business owner out of the equation and pay the staff to make my food directly. They deserve the profit.

I don't have access to the article but would guess that this is about a pushback against that. I've personally begun my own pushback and try to base my tipping on where I think it's reasonable and never give into awkwardness or default values.
